Porosity would be in cast iron not steel, but I have never seen anyone repopping new crankshafts anyway. If there are, chances are Cheena made and then I'd be more concerned with inferior or incorrect steel and/or incorrect heat treat./OEM Ford cranks are induction hardened to 60 Rc. Better of finding a cheap parts tractor or one from a seller parting out and using the one from it. Whatever, plan on having the crank reground and then the proper bearing kit for it.
